The 2010 Civic is coming up for an oil change, and I have two quarts each of M1 EP and AFE available in 0w20. The AFE is in unopened quart bottles dating back at least three years, and I need to use it somewhere. The Civic has suddenly become a 500+ mile per week vehicle, 90% highway, so I am think that this mix should be good for the coming winter and hopefully 10k miles. Any differing opinions?
